With 189 water basins and an average rainfall of over 2,000–4,000&nbsp;mm per year, Malaysia is prone to [[river]]ine, [[Muddy flood|muddy]] [[flood]]s that range from hours-long [[flash flood]]s, to prolonged flooding on flat, low-lying land along major tributaries and main stems. 15 instances of major flooding in the region have occurred since 1926; notable floods include the [[1971 Kuala Lumpur floods|1971 floods]] in and around [[Kuala Lumpur]] that killed 32, affected 180,000 and prompted the launch of flood control projects in the city, [[2006–07 Southeast Asian floods|2006 and 2007 floods]] in [[Johor]] that resulted in 18 deaths and [[Malaysian ringgit|RM]]1.5 billion in damages in addition to the temporary displacement of 110,000 people,<ref>{{cite news|title=Flood and Drought Management in Malaysia |url=http://www.met.gov.my/ClimateChange2007/session1b/Keynote%20Lecture%202%20-%20Ir.%20Haji%20Ahmad%20Husaini%20Sulaiman/K2%20Husaini_p.doc |publisher=Ministry of Natural Resources and Environment Malaysia |access-date=1 August 2008 |date=21 June 2007 |url-status=dead |archive-url=https://web.archive.org/web/20080910042913/http://www.met.gov.my/ClimateChange2007/session1b/Keynote%20Lecture%202%20-%20Ir.%20Haji%20Ahmad%20Husaini%20Sulaiman/K2%20Husaini_p.doc |archive-date=10 September 2008 }}</ref> and major flooding centered around the [[Klang Valley]] in [[2021–2022 Malaysian floods|2021–2022]] that led to 54 deaths, at least RM5.3–6.5 billion in damages and left 125,490 displaced. Flooding has been a major concern in recent decades due to rapid development in river catchment areas that has led to increased surface and river runoffs, increased sediment buildup in rivers, and frequent erosion along river banks.{{Citation needed|date=November 2010}}

Due to weak [[Coriolis force]]s from its close proximity to the equator, direct passages of [[tropical cyclone]]s are rare for the country despite its proximity to the highly active Northwestern Pacific [[tropical cyclone basins|tropical cyclone basin]]. The only tropical cyclones to significantly affect Malaysia since records began were [[Tropical Depression Greg (1996)|Tropical Storm Greg]] in 1996 and [[Tropical Storm Vamei]] in 2001; the former's passage over [[Sabah]] remains the deadliest tropical storm in the country's history, with 238 dead and 102 missing. However, tropical depressions as well as outlying storm patterns generated by passing cyclones have made landfall regularly, often leading to abnormally high rainfall and flooding, such as the tail of [[Typhoon Lekima]] striking the [[Malay Peninsula]] in August 2018, and the path of 2021's [[2021 Pacific typhoon season#Tropical Depression 29W|Tropical Depression 29W]] across central Peninsular Malaysia contributing to [[2021–2022 Malaysian floods|record precipitation and protracted flooding in the region]] between December 2021 and January 2022.{{Citation needed|date=November 2010}}
